A Phase 2 Trial of ENV-101 in Patients With Lung Fibrosis (WHISTLE-PF Trial)
PHASE2ACTIVE_NOT_RECRUITING
The goal of this clinical trial is to evaluate the impact that ENV-101 has on lung function and key measures of fibrosis in adult patients with idiopathic pulmonary fibrosis (IPF). Another goal of this study is to better understand the safety and tolerability of ENV-101 in this patient population.
Study details:
This trial is a 6-month, randomized, double-blind, controlled, dose-ranging trial of ENV-101 in adult patients with idiopathic pulmonary fibrosis (IPF). Patients are allowed to continue treatment with approved standard of care (e. g.
, nintedanib, pirfenidone) during the trial. Patients will be randomized to one of 3 dose levels of ENV-101 or placebo at baseline. The objectives of this trial are to characterize the efficacy, antifibrotic activity, and safety of ENV-101 to select the Phase 3 dose of ENV-101.

Prior history of in situ melanoma, basal or squamous cell skin cancer if treated with curative therapy. 2. Patients with prostate cancer that are managed by surveillance. 3. Patients with ductal carcinoma in situ, treated surgically with curative intent.
- Patients with moderate to severe hepatic impairment (Child-Pugh B and C).
- Smoking (including vaping) within 6 months of study start; current smoker, or unwillingness to refrain from smoking during the clinical trial duration.
- Active or suspected alcohol or drug abuse in the opinion of the Investigator.
- Currently enrolled in another investigational device or drug trial, or less than 3 months from study start since ending another investigational device or drug trial(s) or receiving other investigational treatment(s).
- Presence of active infection at study start or confirmed active human immunodeficiency virus (HIV), Hepatitis B virus (HBV) or Hepatitis C virus (HCV).
- Major surgery requiring hospitalization (according to the Investigator) performed within 3 months prior to study start or planned during the course of the trial. Being on a transplant list is allowed.
- Occurrence of serious illness requiring hospitalization within 90 days prior to study start.
- Current or previous use (within 28 days prior to study start) of the following: 1. Endothelin receptor antagonist 2. Riociguat 3. Prostacyclin or prostacyclin analogue 4. Radiation to the lungs 5. Oral corticosteroids >15 mg/day.
- Use of cyclophosphamide or tocilizumab within 8 weeks, or rituximab within 6 months, prior to study start.
- Use of drugs that are known moderate or stronger CYP3A4 inhibitors or inducers within 14 days prior to study start. Patients must also agree not to eat fruits that inhibit CYP3A4 such as grapefruit, Seville oranges, pomelo and star fruit.
- Patients of reproductive potential who are sexually active and unwilling to use birth control for the duration of the study and for 3 months after their final dose of study drug.
- Females that are pregnant or nursing.
- Patients that are unwilling to refrain from blood or blood product donation for the duration of the study and for 30 days after their final dose of study drug.
- Males who are unwilling to refrain from sperm donation and females who are unwilling to refrain from egg donation for the duration of the study and for 3 months after their final dose of study drug.
- Patients with a history of a severe allergic reaction or anaphylactic reaction or known hypersensitivity to any component of ENV-101.
- Patients who have previously taken ENV-101.

What is the study measuring?
Primary Outcome
| Measure | Description | Time Frame |
|---|---|---|
| Rate of change in percent predicted forced vital capacity (ppFVC) compared to placebo | ppFVC is a measure of lung function | Baseline and Week 24 |
Secondary Outcome
| Measure | Description | Time Frame |
|---|---|---|
| Absolute change in FVC (mL) compared to placebo | FVC is a measure of lung function | Baseline and Week 24 |
| Time to disease progression (absolute decline in ppFVC >10%, IPF-related hospitalization, or death) compared to placebo | Not Specified | Baseline and Week 24 |
| Absolute change in the Living with Pulmonary Fibrosis Symptoms (L-PF Symptoms) Questionnaire Cough domain score compared to placebo | The L-PF Symptoms Questionnaire Cough domain consists of 6 questions regarding a subject's experience with cough over the prior 24 hours. Questions have response options on a five-point numeric rating scale with an anchor of 0 ("Not at all") to 4 ("Extremely"). Total score for the Cough domain is normalized to the range 0 to 100, with higher scores indicating greater impairment. | Baseline and Week 24 |
| Absolute change in the L-PF Symptoms Questionnaire Dyspnea domain score compared to placebo | The L-PF Symptoms Questionnaire Dyspnea domain consists of 12 questions regarding a subject's experience with dyspnea (shortness of breath) over the prior 24 hours. Questions have response options on a five-point numeric rating scale with an anchor of 0 ("Not at all") to 4 ("Extremely"). Total score for the Dyspnea domain is normalized to the range 0 to 100, with higher scores indicating greater impairment. | Baseline and Week 24 |
| Absolute change in the L-PF Symptoms Questionnaire Fatigue domain score compared to placebo | The L-PF Symptoms Questionnaire Fatigue domain consists of 5 questions regarding a subject's experience with fatigue over the prior 24 hours. Questions have response options on a five-point numeric rating scale with an anchor of 0 ("Not at all") to 4 ("Extremely"). Total score for the Fatigue domain is normalized to the range 0 to 100, with higher scores indicating greater impairment. | Baseline and Week 24 |
| Absolute change in total lung capacity (TLC) by chest high-resolution computed tomography (HRCT) imaging compared to placebo | HRCT is a method of imaging which is more precise than chest x-ray in the diagnosis and monitoring of diseases of the lung tissue and the airways. | Baseline and Week 24 |
| Absolute change in % quantitative interstitial lung disease (QILD) by chest HRCT imaging compared to placebo compared to placebo | Not Specified | Baseline and Week 24 |
| Absolute change in % quantitative ground glass opacity (QGG) by chest HRCT imaging compared to placebo | Not Specified | Baseline and Week 24 |
